Silicon Valley's forming alliances with Ford and GM after years of division

A big story has developed in the last decade: Silicon Valley and the car business are converging — high-tech code meets heavy metal.

The latest is that Ford, which — alongside China's Baidu — is investing $150 million in Velodyne, a tech company that makes laser-radar Lidar systems. Ford has been working with Velodyne for a decade and uses the expensive Lidar "pucks" on its fleet or self-driving cars, currently undergoing testing in several state.

Over the past few years, the convergence between car makers and tech companies has accelerated, and this graphic (from CB Insights) shows just how much:

You can see that since late 2015, the density of these collaborations, partnerships, investments, and sometimes outright acquisitions of tech companies by old-school car makers has increased.

Why? It's simple: the General Motors, Fords, and Toyotas of the world are making a lot of money right now, as auto markets boom. And they're taking their profits and investing in an uncertain future, but one whose shape is becoming more clear.

The trend is that city dwellers are increasing the pace at which they use ride-sharing services such as Uber and Lyft. Urbanites haven't traditionally been good car customers, because the don't need vehicles. But they do need transportation. And so traditional automakers are striving to bring them into the fold, as well as avoid being left behind if, say, Uber gets really big.
